D designates avertical post, supporting the frame Aon its upper end. E represents a horizontal frame, through which are passed two eye-bolts, F F, secured and adjusted by nuts f f on their inner ends. The

nut f has an arm, G, by which it may be turned. Through the eyes 0 e of said bolts the post 1) passes, resting against a bracket, 6 attached to the frame E. To raise and lower the post the nut f is loosened, allowing the postto slide through the eyes of the bolt. On each side of the frame E are two clamps, H, consisting of bolts with their inner ends bent to form hooks. O11 their outer ends square crank-nuts I or other suitable fastening devices are placed. These clamps are designed to be secured to the iron bar on which the car-door slides. The lumber is passed in out and out of the car over. the roller B, the roller 0 being used in aiding the arrangement of lumber lengthwise of the car.

I claim as my invention- 1. The combination of the roller B, frame A, adjustable post D, frame E, and clamps H, as andfor the purpose specified.

2. The improved timber-loading and unloading apparatus, having the rollers B 0, frame A, and post D, combined and arranged substantially as specified.
